* Overlaps with BraggingRightsReward: each Pair Unit has [[InfinityMinusOneSword two pieces of exclusive equipment]] which can be obtained by completing each of the challenge maps; the last one has [[InfinityPlusOneSword the strongest drops]] [[UpToEleven which can be used by any team]]. Granted, because of the higher levels of the challenges compared to the main campaign, you'd need to make use of some of the actual techniques listed here to survive, such as the Reiji/Xiaomu, Ulala and Chrom/Lucina strategy and Axel's 150% attack increase. Depending on your strategies, you can use these maps to get the best equipment possible and grind for experience; combining those two together will absolutely destroy the story.

** The Challenge Maps themselves are this for another reason, it is the fastest way to earn gold. Besides the LevelGrinding and the equipment mentioned above, you can repeat the challenge maps to sell the extra equipment from 100,000 to 300,000 gold depending on the level and in last challenge map, the above strongest equipment is worth 500,000 each piece. This can really add up and soon you may get to the point of having MoneyForNothing.

* Really, anyone who can do a barrier-breaking move can be considered as one (seriously, it's ''required'' for [[spoiler: the FinalBoss, who has ''five barrier gauges'')]]:
* Chun-li and Morrigan can be quite damaging in the right hands, and they learn skills faster than anyone else in the game with their first attack skill being Chun-li's [[ChargedAttack focus attack palm strike]] that ''destroys barriers'' (if Chun-li can't destroy it, then it's guaranteed that one of Morrigan's missiles ''will'').
* Ryu and Ken with the same input (down-A) can also enable them to destroy barriers as if it were paper.
* Reiji ([[VideoGame/EndlessFrontier yes, him again]]), and Xiaomu have Accel that guarantees they're going to be one of the first units to act and they learn the barrier busting skill that when you cast it, ''any first hit'' (they have to do the deed) is a CriticalHit ''obliterating an enemy's barrier''. Pair them up with Flynn who has a skill that gives +2 movement to ''all allies on the field'' and watch as hordes of {{Mooks}} and bosses suddenly go down a lot more than usual and pesky [[TimedMission Timed Missions]] suddenly become a lot easier to handle.
** Their Right + A attack can also break 5-gauge shields - that's right, long before Chun-li and Morrigan can get theirs.
* Kogoro and Mii learn a skill for a lower casting cost that destroys an enemy barrier, the Tenzai Style: Ripple. What makes them a bit more special is that they can hit one more square away from the usual 2-square range. They also have an attack that destroys a five-gauged barrier that's available ''[[DiscOneNuke at the start of the game]]'' (Sharinken & Extensions) so it's more of choosing whether you want to break the barrier right away or do it the normal old fashioned way.
* Heihachi's passive support skill allows a unit to ''laugh'' at enemies who have barriers cause they can shatter them. Oh and did you want assurance? He has a support skill (that you need to cast at the skill list) that ''breaks barriers'' nullifying the need to rely on the RandomNumberGod.
* Zephyr and Leanne's Multi Attack is nothing to scoff at, capable of inflicting a lot more damage ''more powerful than what Multi Attack damages'' should be. This is on top of them also having a skill that breaks through barriers like tinfoil. Then there's the fact that their [[MoreDakka ridiculously high hitcount]] allows them to rack up [=XP=] faster than practically every other pair in the game, practically guaranteeing them at ''least'' one use of it every two turns.
* The CriticalHit mechanic in general is this, [[DifficultButAwesome if you can pull it off]].
* Frank and Hsien-Ko[=\=]Lei-Lei work really well with anybody thanks to how simple the execution of their attacks are and their first attack skill that they learn is their Multi Attack. The only problem however is that they're a MightyGlacier unit so they're almost always left behind. The ''real'' GameBreaker is if you let them pair up with [[VideoGame/{{Tekken}} Alisa]] who has a skill that essentially ''gives the unit a lot of speed'', making them go up at least near the first unit to act on a turn.
* [[VideoGame/VirtuaFighter Akira and Pai]] have a skill call Stamping. Stamping can break barriers, that is all.
* Haken and Kaguya have TWO attacks that can break barriers as soon as they are useable(neutral-"A" and left-"A"), combos are easy to chain with their high Tec stat, the ability to attack from three squares away that can be increased to four if Haken's Sniping skill is used, and Love, the only skill which can heal ALL ALLIES on the field to full health.
** Take note, even with all these game breakers, this game is still at NintendoHard level thanks to the fact that bosses hit hard a lot, you don't get a lot of items to use, and your cross point gauge doesn't exactly match up to how they gain their Cross point Gauge. That and you're usually hitting up to 50k per unit ''at most'' when a lot of bosses are usually at 100k HP.

** The Challenge Maps themselves are this for another reason, it is the fastest way to earn gold. Besides the LevelGrinding and the equipment mentioned above, you can repeat the challenge maps to sell the extra equipment from 100,000 to 300,000 gold depending on the level. This can really add up and soon you may get to the point of having MoneyForNothing.

* For even more attack damage insanity, there's also Hibana's skill that costs only 100 SP, but boosts attack by ''75%'' to her associated pair unit. Add in the potential to stack buffs, and you get a team that can cut down bosses like they were nothing.
